IMPROVED TIRE-HEATER.

TO ALL WHOM- IT MA-Y CONCERN:

Be it lrnown that I, P. 1?, HEMS'IREET,' of Galesburg, in the county ofKnox, and State of Illinois, have invented a newand useful Tire-Heater,for heating any kindof tire, for thepurpose of expanding the samebeforeputting in place on the wheel; and I do hereby declare thefollowing to be a full, clear, and exact description of the constructionand 'operaton of the same, reference being had to the annexed drawings,making apart of this specificatioinin which- 1 Figure 1 is a sideplan orview of my machine.

Figure 2 is a sectional view, and

Figure 3 is a view of the bottom. 1

Similar letters of reference indicate corresponding parts. 7

The nature ofmy-invention relates to constructing a machine in whichtire maybe heated much more regular, more rapidly,'and with less fuelthan by the ordinary method.

To enable others skilled in the art to make and use my invention, I willproceed to' the following fuller and clearer description of itsconstruction and operation. p

B B, fig. 3, represents the base or bottom plate ofmy device, which maybe formed of any suitable material or size. 1 v v A-A, fig. 1,represents the outside circular rim raised a suitable height from thebottom plate B.

K K represent legs for supporting the d evice at suitable distancefromthe grounder floor. I

B, fig. 1, represents an inside raised and stationary rim, about thesame height as the outer rim A.

0, fig. 1, represents a movable rim, about the same'height as andfitting closely inside of the rim'B.

D D represent dampersffitting closely over corresponding openings in themovable rim 0.

I E E, figs. 1 and 2, represent the rods which are pivoted at T 'l" foroperating the .dampers D D, by means of the handles H H passing outbeneath the bottom plate, as seen at figs. 2 and I S, fig. 1, representsthe rods crossing each other, lying horizontal, and connected at theends to .the movable rim C, so that when the rods are raised, the rim Gwill be carried .up with them.

L, fig 1, represents a vertical rod connected at the top to the'rods S".p r

F, figs. 1 and 3, represents a lever pivoted at M, and extending beyondperiphery of the bottom-plate B" B, fig. 3, sufficient to grasp for thepurpose of operating. I

0 0, fig. 1, represent rods connecting the rims A and B, at suitabledistance from each other for supporting the tire above the fire, whichis made 'on'the bottom plate B, between the plates Aand B.

N N, fig. 1, represent another series of rods similar to o 0', onlyhinged at one end to enable them to be thrown up, as represented by thedottedline P, in order that tire may be placed on the lower series ofrods. Then the rods N being turnecldown to their place, another set offtir'e may be placed on them, and so other series of hinged rods may heplaced above these again. I

Z represents the chimney, which is supported in place by the arms T T.

Q Q, fig. 1, represent doors, which may be opened to the position of thedotted line B- by means of the lever U, hinged at V, and being drawndown to the position shown bythe dottedline H.

X represents a hand passing around the chimney Z in such way that itmaybe slid up and down on the same, and the lever U is attached to thisband for the purpose of operating it.

y y represent, at fig. 1, rods connecting the band X and the doors orplates Q Q, so that the doors Q, Q, maybe opened and closed by means ofthe lever 'U, which is held ineither position by the slide-ring W.

h", fig. 1, represents a damper in the chimney Z.

P", fig. 1, represents a door on the outer rim A, any number of whichmay be provided for the purpose of placing fuel on the fire, cleaningout, due.

- J J J, fig. 1, represent a series of holes in the bottom plate 1313for the purpose of supplying air to support combustion:

The manner of operating my machine is as follows:

First, by bringing the lever U down to the dotted-line position, andthereby throwing open the doors Q Q, the fuel may then be placed inposition, and the tire may also be slid in, on the red line 4,and'dropped into place. The doors Q are then closed, and the ,movablerim 0 lowered by means of the lever F: The damper I: then being opened,allis favorable to support the most rapid combustion, and in case theprogress of the fire should want to be checked-almost entirely, thedamper h may-be closed, and the movable rim 0 slid up until it strikesthe under side of the doors Q Q, thus cutting off all draught entirely,and keeping the tire warm any reasonable length of time necessary. I

Should any part of the tire be found to not be hot enough, may bebrought up by opening. the damper h", keeping the movable rim C up andclose to top, and opening that one of the dampers D next the cold place,thereby giving draught at that point, andthus bringing the heat to thedesired place.

The doors or lids Q may, if desired, be operated with slides inplace ofhinges.

What I claim as new, and desire to secure by Letters Patent, is

1. The outer rim A, bottom B, lids Q, chimney Z, lever U, rods S, bandX, bars N o, and inner rim B, all constructed, arranged, and. combinedas described and for the purpose set forth.

2. The dampers D, rods T and S, and lever F, with rods L and H, and rim0, constructed and arranged as described, and combinedvvith rim B and Aand bottom B, substantially as described, and for the purpose setforth.

Dated, this 23d day of June, 1868.
